Norbert's Gambit Calculator — USD/CAD FX savings

When you convert US dollars at your broker, the "lazy" conversion often costs 1.5% to 2.0% of the amount. Norbert's Gambit (buy DLR, sell DLR.U) bypasses that fee and gives you a near-institutional rate. This calculator quantifies your real savings and your break-even point. Estimate for guidance only — we quantify a conversion mechanism, not advice to buy or sell.

How does Norbert's Gambit work?

When you hold a Canadian-dollar account and want to buy US stocks or ETFs, your broker automatically converts your loonies into US dollars. This "lazy" conversion is convenient, but it hides an FX spread: the broker applies a worse rate than the market and pockets the difference. In Canada, that spread is often around 1.5% to 2.0%. On $20,000, that's $300 to $400 gone, for a single leg.

Norbert's Gambit bypasses that fee. The classic recipe uses two twin ETFs from the same issuer, traded on the Toronto Stock Exchange: DLR (priced in Canadian dollars) and DLR.U (priced in US dollars). Both represent the same pool of US dollars. The steps to go from CAD to USD:

You buy units of DLR in Canadian dollars.
You ask your broker to journal (move) those units into DLR.U, their US version.
You sell DLR.U and receive US dollars at the market rate.

To bring US dollars back to loonies, you run it in reverse: buy DLR.U, journal into DLR, then sell DLR for Canadian dollars. In the end you only pay commissions (often $0 at commission-free ETF brokers, sometimes ~$9.95 elsewhere) and a thin bid/ask spread of about 0.03% on DLR/DLR.U — instead of 1.5%.

Worked example

Say you want to convert $20,000 CAD to USD to buy a US ETF, at a broker that charges a 1.5% FX spread and $0 commission:

Broker lazy conversion: $20,000 × 1.5% = $300 in hidden fees.
Norbert's Gambit: (2 × $0) + $20,000 × 0.03% = $6 in bid/ask spread.
Estimated savings: $300 − $6 = ≈ $294.

With a $9.95 commission per trade (two trades, so $19.90), the savings drop to about $274 — still a clear win. The math only flips for small amounts: that's exactly what the break-even shown by the calculator captures.

Break-even in a nutshell

Break-even = total commissions ÷ (broker spread − bid/ask spread). With $9.95 per trade (× 2) and a 1.5% broker spread minus 0.03%, the break-even lands around $1,350. Below that, fixed commissions cost more than the spread you avoid. With no commission, the Gambit wins from the first dollar.

Assumptions and limits

This calculator relies on reasonable assumptions for the 2026 Canadian market: a broker FX spread of 1.5% to 2.0% (editable), a bid/ask spread of ~0.03% on DLR/DLR.U, and commissions you adjust to match your broker. It does not account for any journaling fees, occasional price gaps between DLR and DLR.U (the ETF's premium/discount), or the small FX move during the holding window. On the tax side, a currency conversion does not by itself trigger a capital gain, but if you hold DLR/DLR.U in a non-registered account, any value change at sale is a capital gain or loss (taxed at a 50% inclusion rate) that must be tracked in your adjusted cost base (ACB).

Frequently Asked Questions

What is Norbert's Gambit in practice (DLR / DLR.U)?

It's a technique to convert currency at the market rate instead of your broker's rate. You buy the DLR ETF (priced in Canadian dollars) on the Toronto Stock Exchange, ask your broker to "journal" it into its US-dollar twin DLR.U, then sell it for US dollars. Because DLR and DLR.U represent the same pool of US dollars, you get a near-institutional exchange rate, paying only commissions and a thin bid/ask spread.

How much does my broker's "lazy" conversion really cost?

The automatic broker conversion typically charges a spread of 1.5% to 2.0% versus the market rate. On $20,000 at 1.5%, that's about $300 for a single leg. Because the spread applies to both buying and selling, a round trip can cost double. This calculator quantifies that hidden cost from your own amounts.

At what amount is Norbert's Gambit worth it?

The break-even depends on commissions. With zero commission (commission-free ETFs), the Gambit almost always wins. With a $9.95 commission per trade and a 1.5% broker spread, the break-even lands around $1,350. Below that, fixed commissions eat the savings. The calculator shows your exact break-even based on your inputs.

What are the risks (settlement delay, fluctuation)?

The main risk is the settlement and journaling delay: between buying DLR and selling DLR.U, 1 to a few business days can pass (T+1, sometimes longer depending on the broker). During that holding window, the basket's value can move slightly. DLR closely tracks the USD/CAD rate, so exposure is small but not zero. Also check your broker's specific journaling rules.
